Agreed. Soon can be quantified by actual need and of which there is not
much need except for larger packages but adding this would just add
unneeded complication to the system that is already in place.
We are running out of diskspace on event the FTP master site - currently we are at ~1TB. The xz compression gives as significant space saving - so there is already a need.
PS. anyone saying a 1 TB etc. disk is cheap will be ignored.
